  2. Cirrostratus cloud - Wikipedia

    en.wikipedia.org/wiki/Cirrostratus_cloud

    Cirrostratus is usually located above 5.5 km (18,000 ft). Its presence indicates a large amount of moisture in the upper troposphere. [2] Clouds resembling cirrostratus occasionally form in polar regions of the lower stratosphere. Polar stratospheric clouds can take on this appearance when composed of tiny supercooled droplets of water or ...

    en.wikipedia.org/wiki/Cirrostratus_nebulosus

    Cirrostratus nebulosus is one of the two most common forms that cirrostratus often takes, with the other being cirrostratus fibratus. The nebulosus species is featureless and uniform, while the fibratus species has a fibrous appearance. [3] Cirrostratus nebulosus are formed by gently rising air. The cloud is often hard to see unless the sun ...

    Cirrostratus fibratus or also called Cirrostratus filosus [2] is a type of cirrostratus cloud. The name cirrostratus fibratus is derived from Latin , meaning "fibrous". [ 3 ] Cirrostratus fibratus is one of the two most common forms that cirrostratus often takes, with the other being cirrostratus nebulosus . [ 4 ]

    Clouds resembling several terrestrial types can be seen over Mars and are believed to be composed of water-ice. [25] [26] Extremely high cirriform Noctilucent clouds are known to form near the poles at altitudes similar to or higher than the same type of clouds over Earth. [27] High cirriform

  8. Warm front - Wikipedia

    en.wikipedia.org/wiki/Warm_front

    A thickening and lowering of these high clouds into middle-stage altostratus or altocumulus is a good sign the warm front or low has moved closer and precipitation may begin within less than six hours. Once the clouds have thickened to 2,500 metres (8,200 ft) from the earth’s surface, precipitation can begin to fall from heavy nimbostratus ...

    en.wikipedia.org/wiki/Circumhorizontal_arc

    A circumhorizontal arc is an optical phenomenon that belongs to the family of ice halos formed by the refraction of sunlight or moonlight in plate-shaped ice crystals suspended in the atmosphere, typically in actual cirrus or cirrostratus clouds. In its full form, the arc has the appearance of a large, brightly spectrum-coloured band (red being ...
